Hi my name is Bryan, I've been looking into starting a reef and fish tank I have a 125 gallon tank but I'm trying to find as much information as I can. I was thinking about starting with mushroom and polyp. I was hoping to find out best equipment to have I don't mind spending more to avoid mistake. Any help would be appreciated I'm new to the world and want to make sure I have and the advice and information I can get
